This is an adapter for the Bosch quick change vacuum attachment (like that found on the VAC090A) to a 1.5" OD dust collection port. It's a snug fit, and there's a slight taper on the tool side for a solid connection. I uploaded my .step file so you can modify the tool end to suit your needs - if there's interest, I can make some variations to fit different tools, or put together a parametric model. Modeled based on fmMike's design, with a few modifications (changed location/size of quick change detents, added internal overhang to cover lip of vacuum hose).

No supports required if you print it in the orientation that it's imported (tool side down), as there's a small overhang on the vacuum end to prevent clogging. I also aligned the seams to the back, purely for cosmetic purposes.
